bitcoinmarketjournal.com/decentralized-currency I agree that it's not easy to understand cryptocurrency. And it's not something that can be explained in a few minutes. There's lots of info about it available online, and it's helpful to browse the various FAQs. OTOH, there are articles that have lots of hype and not much useful info, from organisations who just want your money. ;)
